The reason why the bigger companies like Microsoft, Apple & Real (to name a few) haven't done anything, is because they know these complaints made by Acacia; really have no legal standing.
One thing you should know is that Acacia makes money on simply buying patents on already existing technologies, for nothing more than profit. This is a perfect time for the government to crack down on companies that exist in this way.
"Software patents pose a significant danger to protocols. In some cases patents become included in protocols by accident - that is, without deliberate intentionality on the part of the protocol developer. In other cases, however, an unscrupulous company or organization may deliberately introduce patented components into a protocol, in an attempt to gain market advantage via ownership of the protocol."
"In order for the protocol to play this role, anyone who wishes to implement and use it must be able to do so freely, and without restrictions. The presence of patented components within the protocol places restrictions on its usage, and therefore serves only to undermine this purpose. Furthermore, the presence of the patent brings an enormously unfair market advantage to the patent holder. By exercising his patent rights, the patent holder can gain financial benefit from competing companies who wish to use the protocol, or can stifle competition altogether by denying the competing company the right to use the protocol at all. "
"Patents are applied to software, not to protocols. It is not possible to patent a protocol; in general only a process or an algorithm can be patented. However, a protocol may include a patented algorithm as an integral part of its specification. In this case, any software implementation of the protocol requires the use of patented software. That is, a patented algorithm is an inherent part of the protocol."

In a time when corporate integrity has been questioned on every level, you have to know that the right thing will happen. I say, once this thing gets put behind us, we should boycott any business with companies that have already bent over to the ludicrous claims made my Acacia and other such profiteers.
